Owns the full lifecycle of operational software products, from concept through production. Builds and tests reliable, user-focused features; scales prototypes; triages issues and identifies root causes; and partners with product teams, mission engineers, architects, and end users to deliver effective solutions. The role requires strong React, TypeScript, and Python skills, performance optimization experience, and collaboration across technical and non-technical stakeholders.

Lead and deliver scalable software solutions for AMO platforms during a ground-up re-architecture. Design and implement verification systems using technologies including Golang, React, TypeScript, .NET, Kafka, SQL, and cloud platforms. Lead a small development team, provide technical guidance and mentoring, ensure code quality and architectural governance, estimate work, and support systems through production.

Develop and support software, automation tools, dashboards, and alarms for cloud infrastructure, cost attribution, and cloud efficiency. Collaborate with cross-functional teams and senior engineers to design reliable systems, APIs, databases, tests, and AI agents. Contribute to architecture and automation strategies while maintaining strong security, communication, and delivery practices.

Leads technical initiatives for Toast’s restaurant scheduling product, designing and delivering scalable full-stack software. Responsibilities include architecture, API and system design, roadmap influence, cross-functional collaboration, engineering quality, performance, and technical leadership. The role also promotes AI-assisted development and improved employee and customer experiences.

Software engineering interns develop and modify software for space, avionics, tactical, satellite command and control, mission planning, and data processing systems. Responsibilities include requirements analysis, architecture, design, coding, testing, integration, documentation, and collaboration within agile teams. Interns participate in company development activities and work on-site five days per week. Experience with programming languages and high-reliability software development is required; cloud, web, frontend, backend, and database technologies are preferred.

Build and operate production-grade Python backend services, APIs, distributed systems, data pipelines, and agentic workflows for an AI observability platform. Own ambiguous projects from prototyping through architecture, testing, deployment, and ongoing operation. Collaborate with product, machine learning, and infrastructure teams, while contributing React front ends when needed. The role requires strong backend depth, distributed-systems expertise, cloud experience, and end-to-end product ownership.

Develop high-fidelity spacecraft simulation software in modern C++ and Python. Build multi-physics models covering spacecraft dynamics, thermal systems, attitude control, propulsion, power, sensors, and actuators. Implement solver architectures and time-stepping algorithms for real-time and faster-than-real-time simulation, maintain multi-language APIs, collaborate with engineering teams, and participate in code reviews and planning.

Leads the Platform Authentication and Authorization engineering team, combining people management, technical direction, and delivery accountability. Oversees identity and access services using OAuth 2.0, OIDC, Keycloak, MFA, SSO, federation, and policy enforcement. Guides software architecture, production operations, secure development, compliance, modernization, and cross-functional delivery while developing engineers and promoting responsible AI-assisted engineering.
